Just for fun: quick, what's the longest word in English dictionaries?

It's Pneumonoultramicroscopicsilicovolcanoconiosis! That's pneumono-ultra-microscopic-silico-volcano-coniosis.

This 45 letter word means the same thing as silicosis, an occupational lung disease. Somehow, I think I'd rather just say silicosis,except when I feel the need to "wow" my audience.
